java - Parse broken HTML Sites with XPath -

-

this question has answer here:

i questions python here , tools found python, new question: need query things html site xpath.

my current code looks this:

url url = new url("http://somesite.com"); connection = (httpurlconnection) url.openconnection(); connection.connect();  document doc = documentbuilderfactory.newinstance().newdocumentbuilder()                                      .parse(new inputsource(connection.getinputstream()));  xpathfactory xpathfactory = xpathfactory.newinstance(); xpath xpath = xpathfactory.newxpath(); xpathexpression expr = xpath.compile("//span[@class='a-class']"); string price = (string) expr.evaluate(doc, xpathconstants.string);

the problem is, page broken or xpath has problems read:

[fatal error] :4:254: entity name must follow '&' in entity reference.
org.xml.sax.saxparseexception; linenumber: 4; columnnumber: 254; entity name must follow '&' in entity reference.
@ com.sun.org.apache.xerces.internal.parsers.domparser.parse(domparser.java:251)
@ com.sun.org.apache.xerces.internal.jaxp.documentbuilderimpl.parse(documentbuilderimpl.java:300)

is there tool can read html sites better? or should use regex on page?

is there tool can read html sites better?

people speak highly of jsoup.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
